1, DSS standard method and the number of units used symbols directly marked. If 0.01 01uF said, some capacitance "R" said decimal point, such as 0.56-resistance micro-law said.

2 Symbols Act, the combination of words and figures to show a pattern of symbols capacity. If p10 said 0.1pF,1p0 said 1pF,6P8 said 6.8pF. 2u2 said 2.2uF.

 3, color or color Central Standard colors capacitor points of the main parameters. The resistor capacitor with the same color standard method. Capacitor : +100%-0--H deviation signs and symbols, +100%-10%--R. +50%-10%--T, +30%-10%--Q, +50%-20%--S. +80%-20%--Z.
